EXERCISING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 444,674, dated January 13, 1891.

Application filed January 2B, 1890 Serial No. 338,348. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE S. SANBORN,a citizen of the United States, residing atLynn, in the county of Essex and Commonwealth of Massachusetts, have invented a new and useful Exercising Apparatus, of which the following is a specification.

My invention relates to improvements in exercising apparatus in which a representation of a human figure is used to receive the blow and the force of said blow indicated by means of a graduated are.

The object of my invention is to produce an apparatus of the above class which will afford the same exercise obtained in an actual boxing contest and at the same time indicate the force of blows received by it.

The accompanying drawings are illustrations of my invention.

Figure l is a side elevation of the entire apparatus. Fig. 2 is a horizontal section on line 2 2, Fig. 1. Fig. 3 is a longitudinal vertical section on line 3 3, Fig. 2.

Similar letters refer to similar throughout the several views.

A is a representation of a human figure constructed of wood or otherlight material of sufficient strength and padded above the belt, so that it may be struck with bare fist. The figure A is rigidly attached to rod Z, which turns freely in bearings b and c. To the rod Z a spring cl is attached,which is also secured to some permanent part of the apparatus. The purpose of the spring d is to maintain figure Ain its forward or normal position, as shown in Fig. 1, and at the same time afford greater or less resistance to the force of the blow upon said figure, according to the tension of the spring, which is regulated by means of a device e, attached to said rod Z, and adapted to Wind or unwind the same upon the rod.

While I prefer to use a coiled spring for the purpose above specified, I do not wish to limit my invention thereto, as it is evident that other forms of springs may be used to accomplish the same purpose.

To the rod la bar or arm fis rigidly attached, one end of which bears against the cross-piece g, which runs freely on rods h.

parts To the ends of the cross piece g the springsa: are attached and also secured to some permanent part of the apparatus. The springs .r are so adjusted with reference to the force exerted by spring d and weight of figure A that when at rest the foot y of said figure is held slightly above the base of the apparatus, bringing it nearly on a level with the other foot. When figure A has been thrown back and is moving under the forward impulse 6o given it by spring cl, the arm f catches on the cross-piece g before the figure has reached the position just described, and the springs 00 begin to act to retard said motion. In this Way I modify the action of spring cl and prevent Rigidly attached to rodl and movable there- 7 5 with is a small arm 2', radial to are 0 and at its extremity almost in contact with the same. When figure A is thrown back by a blow, the force of same may be ascertained by noting position to which arm t' is carried on the are 0.

To further register the force of the blow, so that it may be ascertained after figure A has returned to its normal or forward position, I make use of the following device: In

a circular slit running parallel with are 0 is fitted an elastic strip holding in place on graduated side of said are by slight pressure against the sides of said slit the pointer 07..

The other end of said strip extends through the slit (see Fig. 2) beyond the end of arm 2',

so that arm t'when moved comes in contact therewith (see Fig. 1) and carries the same and pointer 11, attached thereto, around are 0. When arm 7; falls back, pointer to is left in position to which it has been so carried, and 5 the force of the blow received by figure is thus registered on are 0.

I do not consider my invention limited to the particular arrangement of arm i, are 0,

and pointer n, described above, for it is very 10c evident that the same elements with slight modifications can be arranged in several ways to accomplish the same result.

It will be noticed that in my apparatus spring 61 has two functionsto restore figure A to an upright position and by device just described indicate force of blow received by said figure. V

I claim as my invention and desire to secure by Letters Patent in an exercising ap paratus 1. The combination of the base, a rod revolubly mounted thereon, a representation of a human figure rigidly attached to said rod and adapted to move therewith, a spring to restore said figure to and maintain it in its normal or upright position, and aspiring to restrain theforward motion of said figure, substantially as and for the purposes specified.

2. The combination of the base, a rod revolubly mounted thereon, a representation of a human figure rigidly attached to said rod and adapted to move therewith, a spring to restore said figure to and maintain it in its normal or upright position, a short arm carried by said rod, and a graduated are, substantially as and for the purposes specified.

GEORGE S. SANBORN.
